Rapunzel rallies all of Corona together to retake the kingdom from Cassandra. Varian learns that Lord Demanitus made a machine that trapped Zhan Tiri in another world and Rapunzel, Eugene, Pascal, Varian, Lance, Angry, and Red venture to Demanitus' tomb to get the plans. After a mishap with Lance fiddling with a mind-switcher device Demanitus had inside the tomb, they obtain the blueprints and realize that they have to build the machine close to Zhan Tiri and the Coronans proceed to storm the castle. Rapunzel searches for Cassandra, ready to confront her and hopefully save her from her madness, but stumbles upon Zhan Tiri instead. The princess's powers begin to wane due to the impending eclipse, and soon, the Sundrop is concentrated into an opal that appears on her chest in a similar manner of the Moonstone Opal. Meanwhile, the Coronans successfully build the machine, but Hamuel accidentally activates it, sucking everyone, except Eugene and Edmund in.
Zhan Tiri convinces Cassandra to take what is rightfully hers, and she obliges, before imprisoning Zhan Tiri due to her distrust of the demon. Unbeknownst to her, she has freed herself, taking experience from her escape from her 2,000 year imprisonment in the Lost Realm. Cassandra and Rapunzel meet once again in the hallway. Despite Rapunzel's attempts to turn Cassandra away from her destructive path, the two end up engaging in a fierce battle, unleashing their ehanced might against one another.
Meanwhile, the Brotherhood, still affected by the Mind Trap, attack Edmund and Eugene and they race to Cassandra's tower to destroy it: however, Edmund is revealed to also be affected and Maximus rescues Eugene. Eugene gets through to Edmund who willingly destroys the Mind Trap. They return and rescue the Coronans from the Lost Realm.
The fight between Cassandra and Rapunzel quickly makes its way through the castle, destroying many windows, breaking through walls, and eventually climaxes up at Rapunzel's room, when the eclipse became in full effect. As Cassandra manages to grab the solidified Sundrop from Rapunzel, Zhan Tiri suddenly appears and snatches the Moonstone from Cass. Zhan Tiri then grabs and clutches the Sunstone and the Moonstone, rendering both Rapunzel and Cassandra powerless and transforming herself into a giant demon (the debris destroying the portal in the process). She then traps Rapunzel and Cassandra in a golden rock prison and leaves to destroy Corona.
Imprisoned, with Rapunzel, Cass breaks down sobbing, overcome with genuine guilt over her actions, begging Rapunzel to hate her. Instead, Rapunzel embraces Cass. Back outside while the Coronans battle Zhan Tiri (who overpowered them with the Decay Incantation), Rapunzel and Cassandra make up. Inspired by the phrase in Rapunzel's book "Plus Est En Vous", Cassandra takes the broken piece of the moon stone from their earlier fight and gives it to Rapunzel, giving her just enough energy. They battle Zhan Tiri and force her to mesh the stones together at the cost of Rapunzel cutting her hair short again which slams Zhan Tiri's wrists together, sending the wicked demon obliterating into nothingness and black rocks disappear. The stones had became one.
Just as Rapunzel is ready to celebrate, she finds Cass lying limp on the ground, seemingly having perished in the explosion. Not willing to let her fully redeemed friend die, Rapunzel uses the healing incantation to revive Cassandra and heal everyone else before sending it out into space in the process.
Cassandra decides to leave Corona to look for her own destiny and bids farewell to Rapunzel who accepts her title of princess. Eugene becomes the head of the royal guards with Maximus at his side. Varian becomes the royal engineer and creates a heated water system, making Corona the first in the seven kingdoms to have hot running water. Edmund and the Brotherhood return to The Dark Kingdom to rebuild it and Lance decides to adopt Angry and Red as everyone enjoys their happily ever after. Later that evening, Eugene finally proposes to Rapunzel, who happily accepts.
